MPLAB® ICD 2 Header Specification INTRODUCTION This document contains information about MPLAB® ICD 2 headers, which provide in-circuit debugging capabilities for specific Microchip devices. A special ICD/ICE device is connected to a header board to be used with MPLAB ICD2. This device is mounted on the top of a header and its signals are routed to the MPLAB ICD2 connector (Figure1). On the bottom of the header is a socket that is used to connect to the target board.

Target Application Special ICD/ICE versions of selected devices are needed to provide one or more of the following: (cid:129) the built-in debug circuitry that a device may lack (cid:129) additional pins for the clock, data and MCLR functions required for ICD (cid:129) dedicated program/data memory for ICD ICD versions are labeled with an ICD suffix (Device-ICD). For some devices, ICE versions are available (Device-ICE) and may be used with MPLAB ICD 2 as ICD devices. © 2005 Microchip Technology Inc. DS51292L-page 1

MPLAB® ICD 2 HEADERS FOR ICD DEVICES Some devices have no built-in debug circuitry. Therefore, special ICD versions of these devices are required for MPLAB ICD 2 operation. Other devices have built-in debug circuitry and do not require a header to use MPLAB ICD 2. However, some pins and memory must be used to support the ICD function. Therefore, for some of these devices, special ICD versions offering additional pins (and sometimes memory) are available to provide more transparent debugging capabilities. Currently-available headers and their associated ICD devices/supported devices are shown in Table1.

Move circuitry that makes GP1/RA1 high to another I/O pin during development. See device programming specifications for more information. DS51292L-page 2 © 2005 Microchip Technology Inc.

Header Specification HEADERS FOR ICE DEVICES Devices that have built-in debug circuitry do not require a header to use MPLAB ICD 2. However, some pins and memory must be used to support the ICD function. Special ICE versions offering additional pins, memory and emulator functions can be used to provide superior debugging capabilities. Currently-available headers and their associated ICE devices/supported devices are shown in Table2. TABLE 2: HEADER TYPES – ICE DEVICES VDD Header Part Number ICE Device Used Devices Supported Max 64/80 Pin AC162062 PIC18F87J10-ICE PIC18F65J10/85J10 3.6 PIC18F65J15/85J15 PIC18F66J10/86J10 PIC18F66J15/86J15 PIC18F67J10/87J10 INSTALLATION The MPLAB ICD2 header is installed by following these steps: 1. Set up the header board. 2. Connect the header and MPLAB ICD 2. 3. Connect the header and the target board. Set Up the Header Board To set up a header board: 1. If the ICD device is not soldered onto the header, plug the ICD device into the socket on the top of the header. 2. Set any jumpers or switches to determine device functionality/selection as specified in the following sections. 8/14-PIN HEADERS For some headers, device peripherals need to be selected by setting jumper J1 to the appropriate position. This will have the effect of selecting the device. Device Jumper Setting Peripheral Function PIC12F629 2-3 A/D Disabled PIC12F675 1-2 A/D Enabled PIC16F630 2-3 A/D Disabled PIC16F676 1-2 A/D Enabled PIC12F635 2-3 PORTC, Comparator 2 Disabled PIC16F636 1-2 PORTC, Comparator 2 Enabled © 2005 Microchip Technology Inc. DS51292L-page 3

MPLAB® ICD 2 18-PIN HEADERS For these headers, there are no jumpers/switches. The device with the most program memory is always selected. If PIC16F627A or PIC16F628A devices are selected for MPLAB ICD 2 development in MPLAB IDE, the warning “ICDWarn0020: Invalid target device id” may be received in the build window and as a dialog. The reason is the PIC16F648A-ICD device supports PIC16F648A, PIC16F627A and PIC16F628A, but only reports the device ID for the PIC16F648A. Ignore this warning or disable it under the Warnings tab on the ICD Programming dialog. 20-PIN HEADER – PIC16F639 For the PIC16F639 20-pin header, you will need to connect the jumper J3 as specified below. Tool Jumper Setting Function MPLAB® ICE 2000 1-2 Run/program as regular device MPLAB ICD 2 2-3 Run/program as ICD device In addition to being used with MPLAB ICD 2, this header is used with the PCM16YM0 processor module to emulate a PIC16F639 on the MPLAB ICE 2000 in-circuit emulator. Plug the end of the processor module into the header, and then plug the header into the transition socket or directly onto the target board. 20-PIN HEADER – PIC16F785 For the PIC16F785 20-pin header, you will need to connect the jumper J2 to enable the shunt regulator. Device Jumper Setting Function PIC16F785 1-2 Disable shunt regulator PIC16HV785 2-3 Enable shunt regulator 20-PIN HEADER – PIC16F690 For the PIC16F690 20-pin header, you will need to set the S1 switches (Figure2) to enable peripherals and choose devices (Table3). FIGURE 2: S1 SWITCH HARDWARE ENABLE ADC 4kPFM Switch configuration at left shows all USART peripherals enabled, which is the setting to SSP select the PIC16F690 device.

MPLAB IDE will use its selected device to choose the correct device to emulate. Test points are available on this header to check the following: VDD, VDDcore and ground. CAUTION This header cannot be plugged directly into the PICDEM™ HPC Explorer Board or device damage will result. The PICDEM™ HPC Explorer Board is 5V, whereas the ICD device on the header is 3.6V max. Therefore, modification to the demo board is necessary before the header can be used. 1. Switch S3 should be set to ICE. 2. Jumper J2 must be connected as shown to modify the operating voltage. See demo board documentation for more information. +5V ADJ VIN 1 n J2 pi For V = 3.3V: R R = 1.18KΩ (1%) Connect the Header and MPLAB ICD 2 Connect the 9-inch modular interface cable between the MPLAB ICD2 Module and the MPLAB ICD2 Header.

MPLAB® ICD 2 PROGRAMMING NON-ICD DEVICES The MPLAB ICD 2 header can only program the -ICD device, not the regular device. To program non-ICD devices with theMPLAB ICD 2, use the Universal Programming Module (AC162049) or design a modular interface connector on the target. See the appropriate specification for connections. For the most up-to-date device programming specifications, see the Microchip website (www.microchip.com). CALIBRATION BITS The calibration bits for the band gap and internal oscillator are always preserved by the MPLAB ICD2 to their factory settings. MPLAB ICD 2 PERFORMANCE The PICmicro® MCU devices do not support partial program memory erase; therefore, users may experience slower MPLAB ICD2 performance than with other devices. ADDITIONAL INFORMATION Please refer to the MPLAB® ICD2 In-Circuit Debugger User’s Guide (DS51331), MPLAB IDE Help and the MPLAB ICD2 Readme for additional information.
